Wind Lotus & Wind Tulip
Leviathan Energy’s Small Vertical Axis Wind Turbines,
First One to Connect to Israeli Electrical Grid

Field-Proven Wind Lotus Offers More Clean Energy than Others in its Class

Monday, August 23, 2010 – SDE BOKER, Israel – The Minister of Infrastructure, Dr Uzi Landau, will be dedicating the first small wind turbine, the Wind Tulip, into the Israeli grid. Mr. Yigal Shahor, director of the Midreshet Sdeh Boker and Mr. Ronen Reicher, principal of the Sdeh Boker Environmental School will be hosting him. Leviathan Energy Wind Lotus, Ltd., is an Israeli company that invented and designed the turbine, the Wind Lotus It was produced by Israeli manufacturer Isralaser and installed by Baran Raviv.

Dr. Daniel Farb, the Founder of Leviathan
Energy Wind Lotus and new immigrant from
the United States, said, “It is historic that
in the place where Ben Gurion advocated
the use of solar power in Israel, Dr. Hezi
Yitzhak of Midreshet Ben Gurion had the
foresight to purchase a wind turbine made in
Israel for education and student research projects.
These turbines have the additional advantage
over solar of being manufactured in Israel
and providing jobs here. Small wind energy
has even more potential than solar energy to
make the world energy-independent.” He wanted to convey his special thanks to the IEC as well as to Baran Raviv and Isralaser for the support in getting the Wind Lotus set up at Sdeh Boker.


A new regulation pays owners of small wind turbines a special tariff of up to 1.65 shekels per kilowatt hour for 20 years for electricity produced for the grid through a contract with the IEC. The regulation is meant to encourage the growth of distributed renewable energy in Israel and empower citizens in taking part in developing

The Wind Lotus is a vertical axis turbine. This class of turbines has the advantages of being able to respond easily to winds from any direction and with little low noise and vibration crucial for putting on buildings.

Israel has extensive areas that are perfect for small wind turbines. The right small wind turbine offers the following advantages:
• Easy to fit into niche areas where people live
• Almost zero earth footprint if placed on rooftops—perfect for a small crowded country
• Generally moderate wind speeds require turbines that start at low wind speeds.
• Not interfering with military installations

In addition, wind complements solar power. The wind usually peaks in the summer in the late afternoon, when the use of air conditioning is highest, and the output of solar is declining. So it is a wise decision to combine wind with solar for peak shaving of the grid.

Over the course of the simulation and field testing, the Wind Lotus has proven to be a very aerodynamically efficient and cost-effective small vertical axis wind turbine. Designed using advanced aerodynamic modeling; it sets industry-leading efficiency to begin producing electricity at wind speeds of one to two meters per second. This capability, significantly better than other similar-sized turbines, means those users in virtually any location can receive power from the Wind Lotus.

“Because the aerodynamics results in less turbulence, hence less noise and vibration, and improves the energy captured from each wind speed, the Wind Lotus can enable greater participation in the production of clean energy,” said Daniel Farb, CEO of Leviathan Energy. “Our upcoming generation of product, the Wind Tulip, will provide commercial buildings and private users a cost-effective renewable energy solution in many environments. It will be an exportable, world-class product. Combining form and function, the Wind Tulip will be a beautiful turbine that captures the imagination. We are looking for investors to help us move into mass production and establish small wind farms.”

Wind Tulip will be available in both 2.0 and 3.5 kilowatt versions for 30,000 and 44,000 shekels, respectively. It promises a rapid return-on-investment, depending on local wind speed.

The Wind Tulip will have the following special advantages:
1. Customers want something beautiful to work in an urban environment.
2. The Wind Tulip’s low noise and low vibration characteristics make it ideal for rooftop and near-people uses.
3. Safety: The slow but powerful rotation along with the low vibration means that it is unlikely to loosen its bolts and fly away.
4. Low turbulence: Unlike other turbines on the market, they can be placed close together and take better advantage of limited rooftop real estate.
5. Cost-effectiveness: The aerodynamic design is an improvement over other turbines of its class. The price is reasonable, and a wind farm of them with the subsidy can make a 20% return on investment.
6. Because the turbine starts at much lower speeds than competing turbines, it can make more electricity available for the customer.

The founding team of Leviathan Energy reflects the breadth and dynamism of Israeli society and scientific capability, and the cooperation involved in moving the projects forward. The founder, Dr. Daniel Farb, is an oleh chadash from the US since 2005. He founded and funded the Leviathan group of companies to make Israel a leader in many fields of renewable energy. He initiated the concepts of wind flow used by the company and started to file patents. Professor Moshe Rosenfeld of Tel Aviv University is in charge of performing computer simulations. They were soon joined by engineers Dan Schlesinger and Avner Farkash who developed various levels of prototypes and tested them in the company’s test grounds at Rotem Industrial Park in Dimona. Other important members of the founding team are Gadi Hareli, an entrepreneur with vast multi-disciplinary technological experience and electrical engineer who worked for many years in Israeli high tech industry, Kalman Kolman, also an oleh from the US who is a world-class director of manufacturing, and Joe Van Zwaren, formerly of the Ministry of Science, who brought the Internet to Israel.

The company members share the dream of turning the companies into the Nokia of small renewable power generation.

Dr. Farb is looking forward to making Israel energy-independent. “There is no reason not to have these wind turbines on top of every building in Israel. The best way to achieve energy independence is to build these into the infrastructure. The installation is cheaper when part of the initial design. Every roof should have wind turbines.”
